In a plastic sheet protector
Answer:
6
Explanation:
can't be higher or lower than what you started with
Effusion rate, R, is inversely proportional to the square root of the molar mass, M:
R α 1 / √M
Let Ra be the effusion rate of a gas with molar mass Ma and Rb the efussion rate of a gas with molar mass Mb, then:
Ra / Rb = √ [Mb / Ma]
You know Ra / Rb = 1.82 and Ma = molar mass of N2 = 28.02 g/mol
=> Mb = [Ra / Rb]^2 * Ma = (1.82)^2 * 28.02 g/mol = 92.81 g/mol
Answer: 92.81 g/mol
That molecules would be small, no polar molecules
The answer would be B: Walking instead of driving a car to get to the library.
Explanation: Walking instead of driving conserves gas and puts less fumes into the environment.
